To all whom it may concern: Be it known that I, GEORGE F. BALLOU citizen of the United States, and resident o the borough of Manhattan, city of New York, in t e county of New .York and State of New York, have invented certain new and useful lImprovements in Type-Writing Machines, ofwhich the following is a speciicaton.

My invention ,relates .to type-Writing 'maehines and more particularly to type actions, and the invention is in the nature of an iniprovenient .on the ,ty ,e action of Arthur W.

linith; a plication or which .Was lfiled May 15th, 19.04 Serial No. 260,441.

The. lmain object of .my invention is to provide a cmstrnction whereby a close and compact arrangement qof the ity e bars in the basket or -rest'may he provi` edJ lwithout liability of the ty .e bars inter ering or clash- .d or rest `when adjacent oars are operate at about the same time.

To the abone andother ends which lwill heremafterappear, my invention consists in the features ,of construction, arrangements'of parts and combinations of devices' to be ,hereinafter described `and particularly pointed out lin ,the appended claims.

like' 'reference characters indicate corresponding parts in the various yiews, Figure 1 is a vertical front to ,rear sectional View of suiicient of one form ofy typewriting ma chines to illustrate'my invention. F1gS,. 2-7

inclusive are side elevations of the first six type bars from left to rightjand ysonic Of .the associated parts. vFi 8 is an enlarged de tail top plan View xo one ,of the ty e bars proper.4 Fig. 9 ,is -an enlarged detai1 transverse sectional view taken on the line 1x-w of Fig. 2 and looking in the `direction of the arrow at said line. Fig. 10 is a detail top view of ,one of lthe drivers 'with the associated type bar and hanger 4shown in 'sectionand bro en away in part. Fig. 11 is a fragmentary developed 'top plan view showing the type carrying ends of the system ,of the In the drawings thelfr'arne of the machine comprises a ,base 1 prdvlded with upwardly proJecting corner posts 12 that sup ort ya top plate 3. An auxiliary frame 4 is etachabl1 mounted in the nain frame ofthe machine and supports the lvarious parts of the type In theaccompanying drawings, wherein Iin a bearmg) actions. Thus a pivot rod 5 supported -by theaux'iliary frame constitutesl a pivot on whichkey levers 6 /are mounted, each of the key levers bein provided with ,the usual finger key 7. T e key levers coperate with,l

a suitable universal bar 'to actuate an escapement mechanism for a carriage which is supported in the 4to and travels from si e to side thereof in the usual manner and' supports a platen diagrammatically shown at 8 (Fig. 1)'. The

carriage and escapement 'medianlsm maybe of any suitable construction, a showin of which in the present instance .is deemedg necessary.

The auxiliary frame 4 is provided with a segmental Hangs 9 which is perforated for d the reception and free passage therethrough e of threaded stems 10 on hangers 11 for t type bar actuating bell cranks 1 2 which are segrnentally arran ed in order to properly coperate'with di erent type actions. The forward'projecting arm .of each bell crank is connected to .a de ending link 13,' the lower end of said link eing connected at 14 t0 the associatedkeylever 6. The upwardly projecting arm of each bell crank is connecty ed to, a pull rod :orflink 15, the'rear end' of which"-`iscp1voted at ,16 to a driver 17 .of the 'typegban The drivers are'segmentali v`\ai'ranged and are each pivoted ,at .18 to an associated hanger 19 secured to a associate segmental flange 20 on the auxiliary frame i by screws 21. Al coiled contractile restoring spring 2,2 connects each associated driver and pull link 15, one ond of the spring being secured to -the pull link and the opposite en l to the driver. Each driver 17 4is piv'oted ,at

`23 toa type bar proper 24, the forward en of which 1s ivoted at 25 to a l ide link 26. The guide links are segmental and radially arranged and turn on a fixer pivot wire 27 and work in radial slots 28 in a segment 29 formed on the auxilia frame.

From an ins ection of `igs. 8 and 9 it will be `seen that he joint between each guide link ,26 and its Assoc'iated type bar is formed by a' bifurcate portion 30 formed at the front end of the type bar, the cheek plates forming the bifurcated portion being perforated at 31 for the reception of a 1vot pin 25 which passes through the centra' openlng washer 33, said washer .being surrounded y an eye 34 'formed inthe forward end ofthe guide link 26. The jointis plate of the machine i n v plates at this point and` at the rear ends where the plates are brought together yat 38,

y formed by first placing the washer33 within the eye 34 of the guide link and then placing the eye `with the washer contained therein.y

between the cheek lates4 301 formed by the bifurcation in the orward end vof the type i bar.y A pivot pin is then passed through the registered openings in the type bar, washer and guide link and has its ends turned over or riveted as vshown in Fig. 9.

From an inspection of Fig. 10 it will be understood that each driver is formed of two parallel plates 35 spaced apart throughout their length except at the forward ends Awhere they are`brought together as indicated at36', a rivet 37 passing through the the plates being perforated at this' portion to coperate with a pull link l5. A shouldered rivet 39l is received between the plates below the point where the driver is pivoted to its hanger and where the plates are spaced apart.I This vshouldered rivet constitutes means for connecting therear end of the rev'storing spring 22 to the driver. EachA pivot 23 is in the form of a shouldered rivet, shoulders being provided near opposite ends thereof where the enlarged bearing portion the rear end of the driver where it'is connected to the type bar hanger, thus each pivot 18 is formed as a shouldered rivet with an enlarged bearing portion 43 which is received within an opening in the associated hanger 19, the shoulders on the rivet being formed at ,the points where the reduced portions join the enlargement 43; The upset or riveted ends of the pivotA pin firmly unite the parallel plates of t e driver at this point and rigidly connect the pivot pin 18-to the driver. t A stop 44, whic in the present in- Y stance is in the nature of a slight pro'ection formed on the type bar, co-acts with t `e Aend 36 of the 4driver during the last'portion vof the printing stroke in order to rigidly connect the type bar and driver during the last portion of the printing stroke in order that they may move at this time together as one part around the ivot 18. The :free'end of the type bar is ormed with a member 45 apertured to receive a conoidal stem-46 which projects from fa ty e block 47. 1 The conoidal stem of the type lock is formed near one end thereofand just back of the-lower case type 48, the ott-set portion of the ty e block carryingthe upper-case type' 49. y making the drivers in the form of a`two-part or parallel plate driver and making the type 'will also lbar of a single piece instead of vice versa l am enabled to form the type socket of a single piece with the bar instead of riveting it to the bar as in some/structures heretofore made, thus providing a stronger structure in which the socket is not liable to become dislaced or detached at the riveted connection y the constant'hammering of the type b ars against the platen. I .am also enabled to make the 'contactpoints between the driver and type bar at the last portion of the 4stroke stronger than heretofore where a rivet driver is formed are brought together to form a stron and eicient contact 36 which coperates with the contact 44 formed integral with` the type bar proper.l This arrang ment also provides a means for effecting a pro er alinement of the type on each bar and t e effect is the same as lengthening or shortening an ordinary single piece ty e bar for alining purposes. Thus, if eit er or' both of' the contacts 36-44 are filed down, it 'results in decreasing the angular relation between the type bar and river when the parts are in printing position and in increasing the distance between- .the type blocks and the pivot 18 of .the

driver,.thereby slightly elevating the 'type with reference to the printing o1nt. ,These and other advantages accrue om the type action forming -the subject-matter of `my present invention. In thenormal positions of lthe parts the faces of the types bear against an ink pad 50 supported in a metallic trou h lsecured at its ends to 'the top plate o the machine. From an ins ection of Fig. l it will be understood thatt is ink pad is situated in a skewed arc. p.

The type' actions show-n in Figs. 2-7 'inelusive corres ond` to the first six bars, counting :fromfthe eft when the machine is examined from the front, and these type bars are marked with correspondingletters a to f respectively in Fi 2 to 7 and Fig. 11. From an inspection o F igs. 1 to 7 itwill be underistood that the front face of the hanvers'l9- are Aall secured in the same vertical plane in the rear face of the segment 20, sald plane corres ondin lto the dotted line which is coinci ent with the front faces o Athe hangers in Fi 2 to 7. From these figures 1t e seen that the ivots 18 which connect the drivers to' their an ers are likewisesituated in a single vertica plane indicated in Figs. 2 to 7 bythe dotted line' h. The pivots 23 which connect the drivers `to their ty e bars are -arranged progressively nearer tiie front of the machine as the sides of the system are approached. This will beI @tassa understoodfrom a comparison of Figs. 2 to 7 and from an inspection of the line i rep.- resenting a vertical plane which passes through the pivot 23 of the sixth type bar from the left-hand side of the system or that designated specifically by the reference characterj.

As indicated by the dotted line j in Figs. 2 to A7,`ift will be seen that the pivot wire 27 for the various type actions is in a single vertical planeso that each of the guide links 26 turns about a fixed center, all of which are in the same vertical plane. From an examination of these figures with reference to the'dotted line k it will be seen that the forward ends of the type bars extend progressively farther toward the front'of the machine as the sides ofthe system are approached, the distance that one type bar extends beyond the next adjacent bar corresponding substantially' to the distance between the pivotal connection 23 of one type barand' that of the next adjacent bar as the sides of the system are approached. It will also be seen that the guide links 26 are gradually longer as the sides of the system of type bars are approached, the end type bars a havinor the longest links, the type bars` b having slightly Shorter links, the links .slightly decreasing in `length for the.' ve

type bars at each side of the system, and those for the intermediate type bars being of uniform length. The pivots 23 of allof those type bars, except ve at each side of the system, are in the same vertical plane. Y.

From an, ins ection of the dotted line l which passes trou h the lower case type on the type bar f in ig. 7, it will be seen that the live type bars e, al, c, b and'a are brought progressively forwardl toward the 'front of the machine as the side of the system is approached. It will be understood that the type bars at the op site side of the'system are arranged in a 'ike manuel'. From this construction an arrangemelnt such as that shown in Fig. 11 is provided for the free ends of the type bars in the basket so that the types or type blocks, which are at gradu-4 ally `nereasmg angles to their respective type bars as the sides of the system are approached, are brought forward and overlap each other in planes which extend fore and aft of the machine, in order that suflicient clearance ma be given the type blocks in the basket 'an at or near the ink ad without liability of interference when a jacent type bars are actuated at or about the same time. While the distance between the pivots 18 and 23 of the type bars gradually lncreases as the sides of the system are approached, the construction is such, nevertheless, that the distance between a type at the printing point and the pivot 18 of the associated river is the same throughout the system. By the arrangement described tem being fa rt I am enabled ,to assemble a large number of type bars in a com aratively small arc without the liability o adjacent type bars clashing or interfering at or near the basket.

From an inspection of Figs. 1 and l1 it will be seen that the rear free ends of the type bars are situated in a skewed arc which corresponds substantially to the skewed arc of the ink pad, to theskewe'd arc of the pivots 23, and to the skewed `arc of the pivots 25. These so-called skewed arcs are each in the nature of double arcs or each of the arcs is of double curvature, the arc in one direction being formed by the segmental arrangement or mountin of the type actions and the other arc bein ormed vby the staggered arrangement of t e parts by which the ree ends of the type bars are disposed in the manner indicated 1n Fig. 11.
